TalkTalk DSN (79.79.79.79) cannot resolve www.googleadservices.com

[RichardW3]

When I perform a google search on a product e.g. "double glazed sash windows" from any device in my home and click on a sponsored link, I'm presented with a "This site can't be reached www.googleadservices.com's server IP address could not be found  Try: Checking the connection  ERR_N...

I can see the DNS settings on my iMac points to the Router (EERO) and it points to DNS 79.79.79.79 and 79.79.79.80, (these I've tried, but cannot change on my EERO router)

When I add an additional DNS 8.8.8.8 onto my iMac DNS Settings, the problem disappears, great! but I can't replicate this on my other devices (plus I shouldn't need to!)

Why doesn't the TalkTalk configured DNS resolve www.googleadservices.com

OK thanks

Hi Chris, 

Yes I've changed the DNS on the eero router, I was struggling to find the eero secure settings on the app, I was expecting them to be accessible under settings, only to find they were under the home page!

Many thanks

Hi Richard,

How are you getting on, have you tried ferguson's suggestion?

You can change the DNS settings on your eero if you turn off eero Secure, even if only temporarily. Then go to Settings > Network settings > DNS and enter whichever servers you prefer.
